Tulbaghia violacea - Society Garlic, Pond Edge & Border Plant

Tulbaghia violacea, known as society garlic, is a clump-forming perennial from southern Africa with narrow grey-green leaves and clusters of scented, pale lilac, star-shaped flowers from July to September. It holds the RHS Award of Garden Merit. The leaves smell mildly of garlic when crushed, which gives the plant its common name.

Is society garlic a pond plant?

It grows well on the drier top of a sunny pond margin, with the crown at or just above water level (0–1 cm). Do not plant it deeper: a submerged crown is likely to rot. It does equally well away from water, in sunny borders, gravel gardens and patio pots.

Where to plant society garlic

• The top shelf or bank of a sunny wildlife or garden pond
• Sunny, sheltered borders and gravel or Mediterranean-style planting
• Patio containers in gritty, free-draining compost

How to plant and care for it

Plant in spring once frosts have passed. In borders, add grit to heavy soil. At the pond edge, set the crown level with or just above the water. Water while it establishes; after that it copes with dry spells. Divide congested clumps in spring every few years. Watch for slugs on new growth.

Is Tulbaghia hardy in the UK?

The RHS rates it H3, so it is reliable outdoors in milder and coastal parts of the UK. In colder or exposed gardens, mulch the crown in winter or grow it in a pot that can be moved under cover. Cold combined with waterlogged soil is the main cause of losses.

Is society garlic edible?

Yes. The leaves and flowers are edible and have a mild garlic flavour, and can be used in salads and as a garnish.

Which size should I buy?

7 cm and 9 cm bare-root plants arrive without a pot and are the most economical way to plant a group. Potted 9 cm, 1 litre and 3 litre plants arrive growing in our peat-free compost and give a faster display.
